SPECIFICATION forming part of Letters Patent No. 757,274,:1atedApril 12,1904.

Application filed August 7, 1903. I

Toall whom it may concern.-

Be it known that I, EDGAR H. CoT'rnELL, a citizen of the United States, and a resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Machinery-for Cutting and Folding Paper or other Fabrics, of which the following is a specification.

constitutes this invention is more especially intended to be used in connection with a printing-machine in which the printing of the necessary number ofpages for a signature is performed on a continuous web before cutting the latter into sheets.

Machinery embodying the invention in its entirety and in WhatIconsider its most ef fective form comprises a rotary collecting cylinder. or drum for taking sheets cut trans: versely from a web and collecting and imposing the so-taken sheets one upon another on its periphery, astationary table arranged be; 'low .said cylinder and having a downward lattherefrom, a rotary sheet-carrier between said cylinder or drum and said table. for taking the so collected and imposed'sheets from said cylinder or drum, rollers and guides between said carrier and ter, and an endless sheet-carrier running along said table in a direction parallel with the partly overlapping each other are carried in a train and presented together to a cutter by which several of the superposed sheets in the train are out together to'form piles of shorter, sheets, which are carried further by the same carrier to a folder which by one fold folds all An important feature of novelty in this inv'entions of my own, which are the subjects of my United States Patents N o. 732, 338 and No. 7 32,339,. consis the substitution of the stationary lateral yslanting table hereinabove Serial No. 168,610. (No model.)

.mentioned for the horizontal table and the horizontal endless moving apron illustrated in said patents, on which the sheets are deposited in the train and along which they are taken by the carrier to the cutter and folder. The lateral slant of the table renders automatic 'orfacilitates the proper alinement and lateral register of the sheets because of the natural tendency of the sheets when liberated upon the table to descend it by'gravitation to stops provided on the said endlesscarrier for "such alinement and register. I

Other features of the invention consist in certain changes hereinafter described and claimed which the substitution of said slanting table has made desirable, but which may be to a certain extent applicable in connection with the table or apron described in the patents above mentioned.- i

, In the accompanying drawings, Figures 1 and 1* together representa front elevation of cutting and folding machinery embodying my invention; Fig. 2,'a left-hand'side view of'the same; Fig. 3, a transversevertical section in the line 3 3 of Fig. 1; Fig. t, atransverse vertical section in the line 4. 4 of; Fig. 1; Fig. 5, a sectional view of certain details which are less clearly represented in Fig. 4; Fig. 6, a plan view of one of the printed sheets cut from a web and collections of which the example of the invention represented is adapted to cut into smaller sheets and fold; 7, a plan view. of one of such smaller sheets; Fig. 8, a plan view of a train of the printed sheets shown in Fig. 6, illustrating the order of their passage to thecutter and folder for the production of signatures; Fig. 9, an edge View corresponding with Fig. 8.

20 is the'bed'plate supporting the main framing 21, in or on which are the bearings for the cutter-shafts 22, for the shaft-23 of the collecting cylindenor drum 24, hereinafter termed the "cylinder," and for the shaft 25 of the rotary sheet-carrier 26, hereinafterre ferred to as the reel, whichl is furnished with grippers for taking the collections of sheets'ifrom the cylinder 24 and depositing them upon the stationary slanting table 27,

which is suitably supported in the framing 21.

The reel 26 is arranged directly under the cylinder, and the stationary table 27 ,which is arranged at one side of the cylinder and reel, has its upper edge at a level slightly below that of the axis of the reeland has, as shown in Figs. 3 and 4, a lateral inclination downward and outward from said cylinder and reel. The length of the cylinder is at least equal to the width of the web from which the sheets are to be cut. The width of the table is slightly less than the length. of web required for the sheets, and the length of the said table, which runs parallel with said cylinder, is greater than the length of the cylinder, so that at one end it extends, as shown in Fig. 1, a sufiici'ent arranged lengthwisein grippers 30 31 32, Figs.

length beyond the corresponding end of the cylinder to'take in the folder 55. Opposite the lower edge of the table is the lower horizontal run of the sheet-carrier, which'consists of an endless rack 28 and attached grippers 29. The collecting-cylinder 24 is furnished with 3 and 4, for collecting upon it and imposing one upon another in couples the sheets cut by the rotary cutter 33, said grippers being carried by shafts 34,

the cylinder. In the example represented, in which the cylinder is of a circumference equal to the length of web required for three sheets, there are three sets of grippers. For the purpose of opening the grippers to there is provided a stationary cam 35, against which run rollers on the ends of levers 36, provided on the gripper-shafts 34. The closing of the grippers is effected in a well-known for liberatin 42, which is arranged in 5o manner by springs 37. For the purpose of opening the grippers to liberate the imposed couples of sheets there is provided, as described in my patents hereinbefore referred to, atripping-cam 38, Fig. 3, under which the rollers on the gripper-shaft levers pass in the revolution of the cylinder, the said cam being carried byv a lever 39, which works on a stationary fulcrum 40 and. which at proper times the sheets is thrown-into operative position by a cam 41 on'a rotary shaft suitable bearings and which makes one revolution for every twothirds of a revolution of the cylinder. 9

The reel 26 may be,

It is repreof a number of disks 26, fastened upon the shaft'25n; The said reel is represented as furnished with-a single set of grippers 43 a 'd as geared with the cylinder to make onerevolution for every two-thirds of arevolution of the latter. The grippers 43 are like those commonly employed on thecylinders, of printing and folding machines, being carried by a shaft 44, arranged in'bearings in thereel, and they are provided, as. is common and shown, in Fig. 3, with springs, 45

for closing them. For openmg these 11)- receive sh ets from the cutter for the sake 'of light. -ness, of skeleton construction.

, sented as composed pers to receive the collections of sheets from cam 46, and for again opening them to liberate the sheets in time for deposit upon the table 27 there is another stationary cam 46*, a roller 47, provided on the shaft of the said grippers, being carried over these cams at the proper times, respectively," to effect the openmgs.

Betw en the reel 26 and the upper edge of the table 27 there is a set of sheet-supports 48, carried by a stationary bar 49, which runs the whole length of the reel and cylinder and is supported in the framing 21. These sheetsupports have their faces tangential to the reel and have a slant corresponding with that of the table. There is also arranged between the reel and table a pair of rolls 50 5 1 forcarrying the sheets overthe said supports from the reel to the table. ported in suitable bearings in the framing and are driven at suitable speed. Besides the sheet-supports 48 and the rolls 56 51 there are between the reel and the table knockers or pressers 52, which are brought down upon the upper edges of the sheets for the purpose of preventing them from rising from the table when their lower edges strike and are, stopped by the stops 29*, provided on the grippers 29 of the sheet-carrier. The said pressers 52 are carried by a roc'khaft 53, which is supported in suitable fixed bearings, and they are oper- 56, Fig. 5, on the shaft 25 of the reel 26, the said spring acting between an arm 57 on said rock-shaft and a ing, and the said cam acting on another arm 59 on the rock-shaft. The spring keeps the pressers raised at all times except just when the sheets after having run past therolls 5O 51 and down the slanting face of the table have been stopped by their lower edges comtime the depression 56* of the the arm 59 of the-rock-shaft 53' and allows the spring to bring down the pressers upon the sheets. In order topermit the sheet-supports 48 to project, between the rolls 5O 51 as far as the upper edge of the table andthe pressers 52 to project between said rolls and over the said edge, the said rolls aregrooved circumferentially at proper in-- tervals, where said supports and pressers intervene. I a v The carrier, consisting of the endless rack 28, with attached grippers 29, represented of known construe ion. The said rack is arranged opposite the face of the table, where it runs in slideways 60 in a stationary frame 61, supported inbrackets 61* on the mainframing,'and it is carried by upright wheels 62 on axles 63, supported in said frame 61., and is driven intermittently by a spur-gear .64, as will be hereinafter described. It is the pers, at which cam 56 passes lower' run of this carrier which is the opera the cylinder 26 there is provided a stationary These rolls are supated by a spring 54 under the control of a cam ing in contact with the stops on the rack-gripfixed bearing 58 on the frammay be and is to the lower edge offthe table 27.

The grippers 29 are in such number and so I spaced that there may be two to receive each of as many of the shorter sheets 65, Fig. 7, or

of the uncut sections 65 ofthe longer sheets,

Fig.8, which are to form said shorter sheets,

as may be at any time presented one before" another on the table 27, which inthe example represented makes eight of said grippers to be included within the length of the cylinder and two for the portion of the table which extends beyond the length of the cylinder andwhich takes in the folder 55 by which the foldingof the piled sheets on the line 66 to form signatures is effected. The grippers represented (see Figs. 3 and 4) are of the kind which constitute part of the subject-matter of my United States Letters Patent No. 732,338, being, as hereinbefore mentioned, provided with stops 29* and being closed by springs applied on their pivots, said stops serving to arrest the sheets in their descent after their liberation from the rolls 50 51, and "so to preserve the alinement of the successively-deposited sheets.

The cutter hereinbefore mentioned for cutting the long sheets, such as'are represented by Fig; 6, into'the shorter sheets 65 is reprechopping-blade 67,

sented as consisting of a arranged crosswise of-the table and carried by a rock-shaft 68, arranged in suitable bearings in the lower part of the framing. Its location relatively to the length of the cylinder and table is, as may be understood by reference to Figs. 1 and 1*, that its edge which works througha slot in the table is so located that it willcut from a couple or collection of the long sheets taken from the cylinder 24 and deposited upon thetable one of the sections 65 of each of said sheets. The said rock-shaft 68 derives its movement from a cam 69 (see Fig. 4) on a shaft 70, which rotates continuously at the same speed as the shaft 25 of the reel 26, the said cam operating upon an arm 71 of said rock-shaft. i

The folder 55, hereinbefor'e mentioned, which folds into one signature a pile of several of the sheets 65, cut by the cutter67from several deposits of the longer sheets, Fig. 6, consists of a blade which works through a slot provided for italong, the center line of the table and cooperates with the rollers 72, Fig. 3, arranged in bearings under or behind the table, the said blade being carried by the arms 73 of a rock-shaft74, arranged in bearings below the table and being actuated by a cam 75 on the rotary shaft 7 0, before described, said cam acting against a roller;77on' an arm 76 of said rock-shaft 74, the roller being kept in,

contact with the periphery'of said cam by means of a spring 78, Fig. 1, "which acts on another arm 79 of said rock-shaft 74. Below the said rolls 7 2 .there are represented in Fig.-

3 other two rolls 72*, on which and said rolls 72 run tapes 84*, which carry the folded signatures down through upright guides 85* to a packing-table 86, on which they are packed by a reciprocating packer 87; but as this table and packer do not constitute parts of this invention no particular description of themis necessary. r

For opening the grippers 29 to receive'the successive'deposits of sheets upon the table there are provided a series of knockers 80, Figs. 1, 1*, and 4, which are fast upon a rockshaft 81, supported in fixed bearings ,below the table, said knockers being in such number and so arranged on said rock-shaft as to act I upon as many of the grippers-as are opposite the'cylinder during any intermission of the movement of the carrier. For operating this rock-shaft and said knockers said rock shaft has an arm 82, which engages, as shown in dotted outline-in Fig. 3, with a carm-83 on said rock-shaft. For opening the two grippers, which during a movement of the carrier 7 have passed beyond the cylinder and are stationary opposite to the folder 55 during the next intermission of the carrier movement, there are two knockers 80*, Figs. 1 and 3, carried by'a sleeve 84, which is loose on the roclr shaft 81 and is-connected by a rod with one of the folder-arms 73, so that justas the folder iscoming into operation the lastmentioned two grippers are opened to liberate the cut sheets which have'been presented to the folder. r I

The spur-gear 64, hereinbefore mentioned, for driving the carrier-rack28 is represented (see Fig. 1*) as carried. by a shaft 88 and as having the neceSsary intermittent motion imparted to it in the same manner as the endless rack-carrier described in my United States Patents Nos. 732,338 and 732,339, hereinbefore referred to-that is to say, by the mechanicaldevice 89 90, resembling what is known as the .Geneva stop, the wheel 90 deriving constant rotary motion through gears 91 92 93 94 from the rotary shaft 70.

The driving of the several shafts 22 23 25 42 7 O and rolls 72 7 2* may be effected inany suitable manner by properly proportioned gearing-for example, as represented in Fig. 2, in which 'the shaft 42 is represented as the driver and supposed to be driven by suitable gearing from a printing-machine, towhich this cutting and folding machinery is an appurtenance. The shaft 23 of thecollectingcylinder is driven by a gear 95 on said shaft 42, meshing with a gear 96 on said cylinder. This gear 96 drives the cutter-shafts 22 through an intermediate gear 97 and drives the reelshaft 25 by meshing directly with a gear 98 thereon, and motion is transmitted from this gear 98 to a gear 99 on the shaft through a.

train'of-gears 100 101 102 103. The rolls 72 are geared together and driven by the gear 100 through gears 104, and the rolls 72* are geared together and driven by said gear 100 through gears 106 107. The said gears 98 100 101 102 103 104 105 106 107 are repre- I O 24, three couples during every two revolutions,

of said cylinder, and these couples are taken from the cylinder by thereel 26, one couple for each revolution of said reel. These couples are taken from the reel by the rolls 50 51 I and deposited upon the table 27 while the carrier is stationary between itssuccessive movements and the grippers which have arrived in proper positions mitslower run are open.

- The grippers being closed after each deposit, the successive deposits are carried along the table by the succeeding movements of the carrier in the form of a train in which each'couple, as shown in Fig. 9, overlaps its predecessor to the extent of one of the sheet-sections v, 5 65, and after. four deposits have been made there will be beyond the line ofthe cutter 67 four couples of these sections, the first of which couples, numbered 1 in Fig. 9, formed of the tail part of the first deposit, would have 3 been cut off by a preceding descent of the cutter 67, the position of the edge of which is indicated by the line 67 in Fig. 8. "The next descent of the cutter cuts off three couples of sheet-sectionsviz., one couple-from'each ofthe second, third,.and fourth deposits, numbered, respectively, 2 3 4 in Figs. 8 and 9. The next movement of the carrier takes the pile of four couples of. cut sections or sheets 65 to the portion of the table beyondthecyl- 4 inder,'where by the desceiitof' fliefolding-""' blade they are all folded together in the line 66 into a signature of thirty-two pages. This pile in the position in which it is brought for folding is shown at the left-hand end of Figs.

- 8 and 9. Afterthe fourth deposit on the table the operation of the machine is a repetition of that described, a signature being produced after every movement of the carrier by the operations of the cutter and folder.

5 It will be readily understood by those skilled in the art how this machinery may be adapted to the production, fromi l eets cod-taining a greater or less number of pages, "signatures consisting of a greater or lessnumber of sheetsand pages.
